RULE-HOLDER.

- Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed May 8, 1920. Serial No. 379,844.

To all whom it may concern:

Be it known that I, ARTHUR EMERSON, a citizen of the United States, residing at Yale, in the county of Saint Clair and State of Michigan, have invented certain new and useful Improvements in Rule-Holders, of which the followin is a specification.

My invention relates to holders which are used in connection with rules as a means for securing the same to the pocket of the owner to prevent loss, and the objects of my inverr tion are to provide a device of this character which will be more efficient and satisfactory than like devices now in use; which will provide a firm tenacious grip upon the pocket or clothing of the user, which may also be used to hold a gage or a second rule used in connection with the rule by which it is carried; and which can be manufactured very cheaply.

In the drawings forming part of this specification in which like reference characters indicate like parts in the several views:

Figure 1 is a perspective view of a machinists rule with my improved holder thereon;

Fig. 2 is a cross section taken through the holder of Fig. 1;

Fig. 8 is a side elevation showing my holder in engagement with a pocket, and

Fig. 4 is a plan view showing my holder used as a retaining means for a gage or rule used in connection with the rule carrying the holder.

Referring to the drawings, the numeral 1 indicates a machinists rule of the well known type. 2 is my improved holder comprising a sheet metal body, 3, adapted to entirely surround the rule. Part 3 is formed of a single sheet of metal bent into the form described, the meeting edges of the member adjoining centrally of the top surface of the rule and having upstanding parallel flanges 3 projecting at right angles from the plane of the rule. A pin, 4, passes through the two flanges 3 3 near their upper extremity, and serves as a support and bearing for the arm 5. The arm 5, has a finger, 5, adapted to normally pass between the adjacent edges of the base member, 3, and bear directly against the top surface of the rule. A finger piece, 5", is disposed at the rear of the arm, 5, and bearing against the under surface of this finger piece is a coiled spring, 6, the opposite end of said spring bearing against the top surface of the rule. This spring is relatively strong and has an expansive action, .tending to bear the part 5 away from the surface of the rule. A.retaining wire, 7 engages the spring near its lower end, the opposite end of said retaining wire being in engagement with the flanges, 3 3 This retaining wire serves to hold the spring in its vertical alinement and prevents dislodgment of the same.

The action of the spring tends to turn the arm, 5, on its pivot and forces the finger, 5 firmly against the surface of the rule, or the pocket or like article with which the clasp is in engagement. My clasp may be easily released from engagement with the pocket or other article upon the pressing downwardly of the finger piece, 5 My clasp has no parts which can become distorted or readily broken, and its grip while firm upon the article with which it is in engagement is nevertheless easily and quickly releasable. My holder may be readily shifted to various positions on the rule upon releasing the finger, 5, from its engagement with the surface of the rule, but will be firmly retained in any desired position while the said finger is hearing on the surface of the rule.

While I have shown my holder in connection with a metallic machinists type of rule, it is to be understood that the same could wellbe used in connection with any other type of rule without material modification, and without departing from the spirit of my invention.

What I claim as new and dsireto secure by Letters Patent of the United States, is as follows:

1. A rule holder comprising a base member adapted to surround the rule; two flanges projecting at right angles from said base member; a pin carried by said flanges; an arm pivotally mounted on said pin, said arm having at one extremity an article engaging finger adapted to normally bear against the surface of the rule, and at its opposite extremity a finger piece; and a spring having one end bearing against the under surface of the said finger piece and the opposite end bearing against the upper surface of the rule.

2. A rule holder comprising a base member formed of a single sheet of material and adapted to surround the rule; two flanges formed integrally with and projecting at right angles from said base member; a pin carried by said flanges; an arm disposed between said flanges and pivotally mounted on said pin, said arm having at one extremity an article engaging finger adapted to normally bear against the surface of the rule and at its opposite extremity a finger piece; a spring adjacent said base member, one end of said spring bearing against the under surface of the said finger piece and the other end bearing against the surface of the rule; and means carried by the base member for retaining said spring in position.

3. A rule holder comprising a base member adapted to surround a rule, said base member being formed of a single sheet of material and having its abutting extremities extended in parallel relation to form flanges projecting at right angles from the base member; a pin carried by said flanges; an arm disposed between and parallel with said flanges, and pivotally mounted upon the pin said arm having an article engaging finger on one end and a finger piece on the opposite end; and resilient pressure means adapted to bear against a portion of said arm. 7

In testimony whereof I affix my signature.

ARTHUR EMERSON.
